echo $selectedlongdescription; ?>What is it?
This is a virtual hard drive accessible through the serial port. A 32 MB hard drive image (compatible with many emulators) is hosted on a Windows based system. The PC and Apple II are connected via null modem over the serial cable.
Why did I create it?
First I made the rom drive but it wasn't writable and was rather small. This is much slower than the hardware rom drive but allows for easy exchange of data between a real Apple II and emulators. Also, backups are much easier to do on a PC.
How do you get it?
Built it from source. This was an unfinished project started five years ago. It works but only on some models of the IIgs due to the hard coded serial port memory locations. Also, the checksums are not calculated and ignored so data loss is entirely possible and will go undetected.
